| dc.description | In a search for quasi-bound states, or resonances, high-resolution measurements (ΔE~25 meV) of the total positron scattering cross sections have been carried out in the energy region of the first electronically excited states of H<sub>2</sub>, N<sub>2</sub>, CO and Ar. In the case of H<sub>2</sub>, a recent calculation by Varella et al predicts such a resonance in the total elastic cross section near the excitation threshold for the B <sup>1</sup>Σ<sub>u</sub><sup>+</sup> state. We find no experimental evidence for the existence of this resonance and also find similar negative results for the other atomic and molecular targets. |
